Now I have a suggestion for you. What makes a "wall" look like a wall from the bronze age? The art you hang on it. There is a wonderful tutorial inside the thread "Playing around with Perspectives 3" that Ralf added. It describes how to create shearing symbols. If you were to search the internet for "Knossos Frescos" I dare say you would find at least ten useful examples which you could download and use to create symbols to make a "bronze age" wall(s). Once you get the hang of it, you can use the technique to produce any number of culture specific wall decorations. No artistic talent required.

@Nevermet, I cranked these out as prototypes in Bryce. I'd like to see more Perspectives styles but I can see why there are so few. The symbols aren't that difficult to produce as 3d models but it is devilish hard for me to wrap my old brain around the proper orientation angles for the symbols.
